Vacuum valves: Edwards (formely known as BOC Edwards) vacuum valves

Edwards LCPVEK Solenoid Operation Isolation Valves

Edwards (formerly BOC Edwards) aluminium LCPVEK valves are designed for vacuum applications which need a compact, simple, solenoid operation valve to control gas flow. These economical valves are ideal for a number of duties ranging from simple laboratory pump isolation to OEM vacuum system integration and design. Their versatility makes them effective both in vacuum piplines and in chamber admittance applications.

Carefuol design of the solenoid power control and vacuum isolation components delivers efficient magnetic actuation with optimum vacuum performance at an affordable price. This facilitates the use of an electronically actuated valve in many applications where previously this been uneconomic.

Edwards LCPVEK Solenoid Operation Isolation Valves:

• Economical design can be used in low budget applications

• Electrical actuation

• Low power requirements

• Electronic boost power supply

• Efficient magnetic design

• Aluminium body with fluoroelastomer vacuum seals

• 10^-6 100mbar / 8 x10 ^-7 – 750 Torr operating range

• Versatile 24V option
